hi kevin,
   since this week is the first week of new semester, i should go though
each department for checking in schedule.
about the usbrom i think the usbrom memory still should be analyzed in the
following days. it should be basic memory
of libpayload and usb stack. PMM code will be completed in a few days. I
will test it later.
anyway as you said it would be helpful to hear from anyone who is interested
in usbrom project.
